摘要： An apparatus, system, and method are disclosed for determining a catalyst bed temperature. The method may include receiving a current fluid mass flow within an exhaust pipe and a total amount of unburned fuel available for catalytic combustion. The method may further include determining a plurality of fluid enthalpy values corresponding to various locations within the exhaust pipe. The method may continue with calculating an amount of fuel burned on an upstream catalyst based on the plurality of fluid enthalpy values, and determining an amount of fuel remaining that is available for combustion on a downstream catalyst. The method may determine a combustion efficiency of the downstream catalyst based on the temperature rise across the downstream catalyst, and an amount of heat generated within the downstream catalyst based on the combustion efficiency and the amount of fuel remaining that is available for combustion on the downstream catalyst. The method may conclude with determining a downstream catalyst bed temperature based on the net heat generation, the fluid mass flow through the downstream catalyst, and the thermal response of the downstream catalyst.

摘要： A food winding apparatus, system, and method of forming a rolled food item utilizing a slotted spool or cup and a push plate to eject the rolled food item from the spool. A food winding unit utilizes a motor to rotate a slotted spool. The leading end of a supported strip of food is detected by a sensor and directed into the slot of a spool. A micro-controller triggers a motor in response to the sensor signal to rotate and form a rolled food item after a predetermined number of rotations. An actuator is activated to displace an ejection plate to eject the rolled food item from the slotted spool. The winding unit can be integrated into a system including an extruder to deposit food onto support strips, a series of conveyors, and a rotary knife to cut the supported strip of food into predetermined lengths suitable for being rolled into a food item by the winding unit.

摘要： A method for modifying a NOx adsorber regeneration triggering variable. Engine operating conditions are monitored until the regeneration triggering variable is met. The adsorber is regenerated and the adsorbtion efficiency of the adsorber is subsequently determined. The regeneration triggering variable is modified to correspond with the decline in adsorber efficiency. The adsorber efficiency may be determined using an empirically predetermined set of values or by using a pair of oxygen sensors to determine the oxygen response delay across the sensors.

摘要： A system, method, and software for triggering regeneration of an adsorber connected with a flow of exhaust from an engine. An exhaust sulfur flow rate module estimates a sulfur accumulation rate associated with an adsorber as a function of a flow of fuel. A sulfur removal rate module estimates a sulfur removal rate associated with the adsorber. An accumulated sulfur loading module includes a counter the value of which is increased as a function of the sulfur accumulation rate and decreased as a function of the sulfur removal rate. A combustion manager module controls an engine to regenerate the adsorber once the counter reaches an upper threshold value.

摘要： A system, method, and software that rapidly heats a diesel oxidation catalyst unit to an effective operating temperature at engine startup is disclosed. Upon ignition of an engine an electronic control unit is operable to lower a fresh air flow target value to a reduced fresh air flow target value as well as lower a valve opening limit of an exhaust gas recirculation valve to a reduced valve opening limit. The electronic control unit monitors a temperature value of a flow of exhaust entering the diesel oxidation catalyst unit until the temperature value reaches a first predetermined threshold value. After reaching the first predetermined threshold value, the electronic control unit causes the fuel system to set post-injection fueling to a predetermined post-injection fueling value until the temperature value of the flow of exhaust entering the diesel oxidation catalyst unit reaches a second predetermined threshold value.

摘要： The present invention provides for adsorber catalysts arranged in parallel. The exhaust flow from the engine is divided in a predetermined ratio between the two catalysts during lean operation (e.g. 50-50). At a predetermined regeneration time (for example, when the adsorber catalyst is 20% full), the exhaust gas flow is reduced through the parallel leg that is to be regenerated (e.g. 20-80). A quantity of hydrocarbon is injected into the reduced-flow leg in order to make the mixture rich. Once the leg has been regenerated, the flow distribution between the parallel legs is reversed, and the other catalyst leg is regenerated while the other side (which is now clean) receives the majority of the exhaust flow. Once both catalyst legs have been regenerated, the exhaust flow is adjusted back to normal (e.g. 50-50) until the catalysts are again ready for regeneration and reduction. A catalytic soot filter is positioned downstream from the adsorber. The heat generated by the regenerating adsorber is transferred downstream to the soot filter, thereby heating the soot filter above the temperature required for regeneration. Additionally, any hydrocarbon that slips through the adsorber is burned in the catalytic soot filter, further raising the temperature. Such burning of the hydrocarbon slip in the catalytic soot filter obviates the need for a diesel oxidation catalyst, thereby reducing system cost and package size.
摘要翻译：本发明提供了平行布置的吸附剂催化剂。来自发动机的废气流在稀薄运行期间以两个催化剂之间的预定比例被分配（例如50-50）。在预定的再生时间（例如，当吸附剂催化剂充满20％时），废气流通过待再生的平行腿（例如20-80）而减少。为了使混合物富集，将一定数量的烃注入到减流气流中。一旦腿已被再生，则平行腿之间的流动分布相反，并且另一个催化剂腿被再生，而另一侧（现在是清洁的）接收大部分排气流。一旦两个催化剂支路已被再生，排气流量将被调整回正常（例如50-50），直到催化剂再次准备再生和还原。催化烟灰过滤器位于吸附器的下游。由再生吸附器产生的热量向下游传递到烟灰过滤器，从而将烟灰过滤器加热到再生所需的温度以上。此外，任何滑过吸附器的烃在催化烟尘过滤器中燃烧，进一步升高温度。催化烟尘过滤器中碳氢化合物滑移的这种燃烧消除了对柴油氧化催化剂的需要，从而降低了系统成本和包装尺寸。

摘要： A system and method are provided for controlling regeneration of exhaust gas aftertreatment components coupled to an internal combustion engine. For example, the particulate load of a particulate filter is monitored and a road speed of the vehicle is determined. If the particulate load is greater than a particulate load threshold and the road speed is greater than a road speed threshold, regeneration of the particulate filter is initiated. As another example, the sulfur oxide load (SOx) of a NOx catalyst is also monitored, and if the SOx load is greater than a SOx threshold while the particulate filter is being regenerated, regeneration of the particulate filter is terminated and SOx regeneration of the NOx catalyst is initiated.
